Baby photos? Political rants? Food snaps, surely?
All likely to ruffle the feathers of Facebook users the world over, but none can claim the top prize of the most annoying "form" of post.
In the Rantic.com's survey of 10,000 Facebook users, that hated prize went to 'Personal Problems' - those ill conceived, 30-word howls into the darkness of social media, desperately seeking out an "U ok hun?" comment.
Of the Facebook users surveyed, 62 per cent of men and 67 per cent of women said that personal rants were the most annoying.
The survey went on to negotiate some other bizarre Facebook habits, illustrated in full below. If you're thinking of sharing it on your page, best accompany it with some words of positivity. Mix it up with a smiley emoji or something.
